Numeric analysis of the global stiffness of group purlin-sheeting in lateral steel panels

This paper presents an evaluation of the behaviour of lateral panels of steel buildings starting from computational modeling using the purlin-sheeting group in the longitudinal contention. The sheeting was fastened on 2nd and 5th waves and also in all waves. The sheeting was fastened in purlin and this system connected in the frame of the building to guarantee the functionality as a rigid panel, action diaphragm. It was also verified the behaviour of lateral panels, with traditional braced system using the same dimensions of the panels diaphragm. The panel was analyzed with dimensions of 4.0, 5.0, 6.0 and 7.0 meters, using the software SAP2000NonLinear. The results showed an increment of 84% related to the system traditional braced.
